DENTIFRICE.

No Drawing. Application filed November 15, 1919, Serial No. 338,364. Renewed February 28, 1923.

To all whom it may concern:

Be it known that I, OSCAR F. SCHMID, a citizen of the United States, residing at the city and county of Jackson and State of 6 Michigan, have invented certain new and useful Improvements in Dentifrices, of which the following is a specification.

This invention relates to improvements in dentifrices.

10 The objects of the invention are:

First. to provide an improved antiseptic dentrifrice which shall be very effective in cleansing the teeth.

Second, to provide-an improved composition dentrifrice'whi ch will remain soft and sufficiently fluid for free use in a collapsible tube for an indefinite time.

Third, to provide in such an improved dentifrice a composition which shall be specially effective in preventing and removing the tartar from the teeth.

Further. objects and objects relating to details will definitely appear from the detailed description to follow.

My improved dentifrice consists of the following ingredients:

I recommend first making a massing paste of the starch thereby thoroughly hydrating 40 same, after which the. other ingredients are.

thoroughly admixed and ground in an ordinary paint or roller grinding machine until the ingredients are all reduced to an iments a substantial palpable smooth mixture. The oil is thereby emulsified.

It is found that, owing to the presence of the oil in which the other ingredients arethoroughly mixed and ground, the mixture will not harden in the tube but remains soft indefinitely; providing an antiseptic nonan abrasive polishing dentifrice.

It is also found that by a repeated application of aforesaid oil or this dentifrice to teeth on which tartar has accumulated, the tartar becomes soft, crumbles and is removed by the brush in polishing the teeth. The mineral oil used is white and tasteless. being preferably white Russian mineral oil.

Having thus described my invention, what 1 claim as new and desire to secure by Letno ters Patent, is:

1. A tooth paste consisting of the following ingredients: chlorate of potash 12%, precipitated calcium carbonate 33%, glycerine 10%, sugar 10%, mineral oil 5%, men- 5 thol 5%, flavoring 14 starch 3%, gum tragacanth .570, water 24%70.

2. A tooth paste containing chlorate of potash, preipitated calcium carbonate in a suitable body reduced to a paste, and a white tasteless mineral oil intermixed and emulsified therein. 7 I

3. A tooth paste containing chlorate of potash, precipitated calcium carbonate in a suitable body reduced to a paste, and a min- 15 eral oil intermixed andemulsified therein.

4. A tooth paste containing in its ingredipercentage of emulsified tasteless mineral oil.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesscs.
